And every night, I look at the photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or printing
Reading and vocabulary
2 Paper was first created about 2,000 years ago in China. After its invention, people started to write on paper to make books. In those days, books were only produced one at a time by hand. As a result, there were not many books, and they were expensive. So, few people had the chance to learn to read.
Reading and vocabulary
3 Printing was invented in China during the Sui and Tang Dynasties. Later, developments in printing made it possible to produce books more quickly and cheaply. A trade in books resulted, and more people learnt to read. Knowledge and ideas spread faster than ever before. In a way, we can compare the invention of paper and printing to the introduction of the Internet in the twentieth century.

4 Although the Internet is still young, it is growing very fast, and may become more powerful than printing. A much larger amount of information can be stored in more varied forms on the Internet than in books. Someone with an Internet connection can find information much more easily than they can find it in printed forms. And the machines we use to read it are now small and light, often smaller and lighter than a single book.

Possible answer
It’s hard to imagine a world without printing because we have so many printed things now, for example, menus, comics and schoolbooks. Paper was first created about 2,000 years ago, but books weren’t printed at that time. They were written by hand, so few books were produced and, as a result, few people could read. Printing was invented during the Sui and Tang Dynasties. After printing developed, books were cheaper, so more people learnt how to read. Today, the Internet is growing very fast. A much larger amount of information can be stored in more varied forms on the Internet than in books. As a result, in the future, the Internet will probably be more powerful than printing.
